For storage I will probably go with shucking the drives out of WD Easystores. I know Plex suggests a CPU passmark of 20p stream, but I would want enough cushion to stream 4k content.
I know FreeNAS likes RAM so I would probably go for 32 or 64gb depending on what people think. I was planning on using FreeNAS and to use Plex for media streaming as it seems to be the most popular.
Synology Drive: Works for my needs and is enough original Dropbox-y now that Dropbox is bloated and a client resource hog.Moments: I'm lazy and just want something similar to Apple iCloud/Photos.Video Station/DS video: cos the family finally use this in preference to iTunes library content (cos I stopped updating that).Plex*: because it works well and tags easier than VS.Media Server*: music serving to my HEOS devices.Audio Station/DS audio: it can stream direct to UPnP/DLNA speaker and Airplay (hey even my Airplay 2 Apple TVs are working again when PIN access is enabled), plus Casting.
